Association studies among yield and its component characters in Indian mustard [Brassica juncea (L.) Czern and Coss]

Abstract

The present study was conducted to gather more knowledge of correlation between yield and its contributing traits and themselves which is useful in selecting superior plant type which could surpass existing agronomically accepted varieties. A set of 40 genotypes of Indian mustard [Brassica juncea (L.) Czern and Coss] were grown in the years 2003-2004 and 2004- 2005 at KVK, Mathura Research Farm. The experiment was planned in randomized complete design with three replications. Each genotype was planted in two rows of 3 meter length. The spacing between and within lines were 30 cm and 15 cm, respectively. Observations were recorded on 5 randomly selected plants per genotype per replication for days to flower, days to maturity, plant height, primary branches per plant, secondary branches per plant, siliqua on main raceme, siliqua length, seeds per siliqua, 1000-seed weight and seed yield per plant. The correlation coefficients and their significance were computed as per the procedure given by [1].
